From Idea to App: Creating iOS UI, Animations, and Gestures

Book Description

Because iPhone development is so young, right
now apps are typically designed, developed and deployed by a single
person (or very small development team.) The designers are the
developers and vice versa. This book will leverage this distinction
by teaching designers how to design on top of native iOS metaphors,
tools and UI, while teaching native developers appropriate
application design and asset preparation.
